[technical field]

The utility model relates to a kind of building unit, refers in particular in the drainage pipe circuit, with the things such as the sandstone in the gutter, mud, the rubbish circular catch-basin of the prefabricated assembling type reinforced concrete being convenient to clear up that precipitates.

[background technology]

Catch-basin is structure important in the underground pipeline, and the performance of city function, the protection of environment and people's life are had important impact.At present, China's underground pipeline catch-basin also relatively backward with material and construction technology, main adopt to build by laying bricks or stones with loam brick at the scene form, have more problem: at first, loam brick intensity is low, poor durability, easy to leak, underground soil layer and water quality are impacted, and maintenance cost is also high; Secondly, need the workman scene to build by laying bricks or stones, Mechanization Level is low, and the field operation time is long, the wet trade workload is large, and curing time is long, is unfavorable for the requirement that road shortens the construction period, lets pass fast, even the environment around the impact, makes troubles for people's life; Moreover fired clay brick damages the farmland in a large number, causes the table soil resource to run off in a large number.Therefore, we need a kind of convenient, durable, saving table soil resource of constructing, free of contamination Novel sink sand drain to remedy the deficiency of brick type catch-basin.

[utility model content]

The purpose of this utility model is to be to overcome the deficiencies in the prior art, provides that a kind of construction is convenient, durable, saving table soil resource, the circular catch-basin of free of contamination prefabricated assembling type reinforced concrete.

In order to solve the technical problem of above-mentioned existence, the utility model is taked following technical proposals:

The circular catch-basin of a kind of prefabricated assembling type reinforced concrete includes at least one pair of gutter, and from top to bottom successively at the bottom of cylindrical well seat and the bottom cylindrical well with riffler of the round manhole cover that gets up of docking, hollow; Preset the reinforced concrete structure of cage muscle in described shaft bottom and well seat are, and respectively by the large cylinder of upper end, the taper cylinder of middle-end and the small cylinder of lower end form; Be provided with to accept the groove of well seat at the large cylinder inwall in described shaft bottom, at top, described shaft bottom, well seat bottom respectively correspondence be provided with upper and lower arc docking groove, described gutter one end just is stuck in the drainage hole that corresponding a pair of upper and lower arc docking groove surrounds and uses cement seal.

In the improvement project to the circular catch-basin of above-mentioned prefabricated assembling type reinforced concrete, the diameter of described gutter is 200---2000mm.

In the improvement project to the circular catch-basin of above-mentioned prefabricated assembling type reinforced concrete, described gutter is the flat mouth pipe, and the opening at its two ends is flat mouth.

In the improvement project to the circular catch-basin of above-mentioned prefabricated assembling type reinforced concrete, described gutter is bell-and-spigot pipe, and the one end is flat mouth, and the other end is horn-like opening.

Compared with prior art, the beneficial effects of the utility model are: it is to produce in advance steel concrete shaft bottom and well seat with cage muscle and concrete in template, directly assemble with corresponding gutter at building-site when needing, do not need to carry out at the scene a large amount of wet trades, realize the pipeline prefabricated construction, greatly accelerated construction speed, and replaced loam brick mortar structure in the past with reinforced concrete structure, intensity is high, good endurance, long service life, maintenance cost is low, has also saved the table soil resource; Moreover the well body utilizes the concrete sealing by monobloc cast between well body and the gutter, and isolated sewage is to groundwater pollution; In addition, the utility model entire body adopts circular configuration, and is strong to the ability to bear of soil body side pressure, further strengthens its anti-pressure ability.

Below in conjunction with the drawings and specific embodiments the utility model is further specified:

[specific embodiment]

The utility model is the circular catch-basin of a kind of prefabricated assembling type reinforced concrete, shown in Fig. 1 to 6, include at least one gutter 1, and from top to bottom successively the cylindrical well seat 3 of the round manhole cover 2 that gets up of docking, hollow and bottom with the cylindrical well of riffler 41 at the bottom of 4;

Preset cage muscle

5,6 reinforced concrete structure in described well seat 3 and shaft bottom 4 are, and respectively by the

large cylinder

31,42 of upper end, the taper cylinder 34 of middle-end, 46 and the

small cylinder

32,43 of lower end form; Be provided with to accept the groove 44 of well seat 3 at large cylinder 42 inwalls in described shaft bottom 4, at 4 tops, described shaft bottom, well seat 3 bottoms respectively correspondence are provided with, arc

lower docking groove

45,33, described gutter 1 one ends just be stuck in corresponding a pair of on, arc lower docking groove 45, also use cement seal in 33 drainage holes that surround, can find out the quantity of gutter 1 and upper, arc lower docking groove 45, the 33 drainage hole quantity that surround are corresponding, at the present embodiment one, in two, gutter has two, correspondingly, on, arc

lower docking groove

45,33 drainage holes that surround also have two.

Directly make by template and equipment in factory in well seat 3 of the present utility model, shaft bottom 4, in template, put into respectively cage

muscle

5,6 by making requirement first, then injecting the concrete material that stirs in template (is formed by certain ratio stirring by sand, stone, cement, breeze, water reducing agent and water, be concrete), respectively moulding is built in shaft bottom 4 and well seat 3.When install and use in the building site, first gutter 1 one ends are lain in a horizontal plane in the upper arc docking groove 45 in shaft bottom 4, then lift well seat 3 and cover on shaft bottom 4, use again cement good seal drainage hole peripheral, cover at last the installation that well lid 2 has namely been finished circular catch-basin.

The utility model in use, rainwater flow in the sand drain from the outside, the foreign matter that carries in the water (such as things such as sandstone, mud, rubbish) in the shaft bottom 4 the precipitation, drain by gutter 1 through the rainwater of precipitation process.The foreign material such as 4 sandstones that precipitate, mud, rubbish need to be focused on by the related personnel at set intervals in the shaft bottom, guarantee the unimpeded of drainage pipe.

As seen from the above, the utility model produces steel concrete shaft bottom and well seat in advance with cage muscle and concrete in template, directly assemble with corresponding gutter at building-site when needing, do not need to carry out at the scene a large amount of wet trades, realize the pipeline prefabricated construction, greatly accelerated construction speed, and having replaced loam brick mortar structure in the past with reinforced concrete structure, intensity is high, good endurance, long service life, maintenance cost is low, has also saved the table soil resource; Moreover the well body utilizes the concrete sealing by monobloc cast between well body and the gutter, and isolated sewage is to groundwater pollution; In addition, the utility model entire body adopts circular configuration, and is strong to the ability to bear of soil body side pressure, further strengthens its anti-pressure ability.
